Another example of Earth’s mantle heterogeneity is two anomalous regions—called Large Low Velocity Provinces (LLVPs)—that stretch for thousands of kilometers at the base of the mantle.

By combining a model of mantle convection, including a reconstruction of how tectonic plates have moved over the Earth's surface over the last billion years, the study has been able to show that ...

Overall, Professors Sun and Tkalčić determine that mantle convection is the primary cause of Mars's unusual dichotomy, not giant impacts as the alternative hypothesis suggests.

A new study, using convection models, shows that Earth’s collision with the protoplanet Theia some 4.5 billion years ago, might’ve triggered early subduction in Earth’s crust.

A 3D view of the blob in Earth’s mantle beneath Africa, shown by the red-yellow-orange colors. The cyan color represents the core-mantle boundary, blue signifies the surface, and the transparent ...

However, little was known about what they were made of, when they sank and what role they might play in mantle flow, known as convection, said Dr. Sujania Talavera-Soza, lead author of the new ...

Gigantic hidden fortresses discovered 1,800 miles underground in Earth's mantle, rewrite how the planet's interior works.

Instead, the Moon-forming giant impact appears to be the origin of the early mantle’s heterogeneity and marks the starting point for the Earth’s geological evolution over the course of 4.5 ...

V. Trubitsin, M. Kaban and M. Rothacher: "Mechanical and thermal effects of floating continents on the global mantle convection", PHYSICS OF THE EARTH AND PLANETARY INTERIORS (Vol. 171, S. 313-322).

But even mantle convection proponents recognize that that amount of internal heat-energy is insufficient to drive large-scale tectonics. And there are other problems with using convection to ...
